You could have done this part as well with a for loop, like this:
function averageWordLength(array) {
if (array.length === 0) {
return undefined;
}
var sumLetters = 0;
for (var i = 0; i < array.length; i++) {
sumLetters += array[i].length;
}
return sumLetters / array.length;
}

It was a good beginning. With a for loop, you would probably have done it till the end.
Here is the solution to do it with a for loop. Don't be afraid of it! ;)
function uniquifyArray(array) {
var newArray = [];
if (array.length === 0) {
return undefined;
}
for (var i = 0; i < array.length; i++) {
if (newArray.indexOf(array[i]) === -1) {
newArray.push(array[i]);
}
}
return newArray;
}

Well done! You understood the notions in the exercise. Keep going this way! |
